equal advantage for working pulp or slimes,

it is of particular utility in its action on the latter which ordinarily is a waste product.

Inthe drawings accompanylng and forming part of this specification I show in detail one form of embodiment of the invention which, to enable those skilled in the art to practice the same, will be set forth in detail in the following description, while the novelty of the invention will be included in the claims succeeding said description.

In the drawings: Figures 1 and 1 represent collectively an ore concentrator in side elevation involving my invention. Figs. 2 and 2* illustrate together a top plan view of the same. Fig. 3 is a transverse section on the line 3-3, Fig. 2 Fig. 4 is a similar view on the line 44 of said Fig. 2".

Like characters refer tolike parts throughout the several figures of the drawings.

The ore concentrator in the present instance is m-a-de in the form of an endwise' or longitudinally reciprocatory or vibratory table, the longitudinal or endwise movement of the table facilitating the stratification of the pulp or slimes thereon and also feeding the same from the head toward the tail end of said table and, in practice, I may provide any suitable form of head motion for giving to the table the action indicated. In Figs. 1 and 2 I have indicated conventionally a head motion, the same being denoted in a general way by 2 and resting on and being securely fastened in some suitable way to the foundation or pier 3 which may, for example, be made of concrete. The table includes what might be considered a primary section as 4 and a secondary section as 5, the pulp or slimes being initially supplied to the primary section 4 and being worked therealong on to'and then along the secondary section 5, the Stratification of the mass or material and the final washing of the mineral values taking place on said secondary portion which may, therefore, aptly' be termed a finishing member. While the primary portion 4 may be disposed in any suitable manner, I prefer that it be at an inclination downwardly from the head end toward the tail end of the table, as an advantage follows this positioning of said primary portion. The secondary or finishing portion of the table will be hereinafter described in detail.

/I may arrange opposite to each other at. suitable intervals any desired number of piers or uprights as 6 of cement or other suitable material, the pairs of piers being shown as bridged by brackets as 7 which are connected to said piers in any desirable way and which in turn sustain the stringers 8, said stringers generally consisting of channel irons. The lower ends of the links 9 are flexibly connected to these stringers or channel irons 8, while the upper ends thereof are similarly connected to said primary section 4 underneath the same between the sides thereof, all as indicated in Fig. 3.

The finishing portion 5 is made up of flexibly connected sections united on diagonally disposed hinge lines as 10 which converge toward the extreme forward end of the table and which are shown clearly in Fig. 2

In addition to the piers 6 to which I have previously referred there is a second pair of piers 6 (see Fig. 4) bridged by a bracket or strut as 7 resting on the same, said bracket or strut 7 supporting the stringers 8 The lower ends of links as 9* are flexibly connected with the stringers or channel irons 8 while their upper ends are similarly connected with the laterally intermediate part of the finishing portion 5 of the table, all as indicated clearly in Fig. 4.

In Figs. 1 and 4 I have shown a. second pair of piers 6 upon which are superimposed and securely fastened brackets as 7 b to which are pivoted stringers or channel irons as 8*.

likewise connected with the lateral parts of the finishing portion 5 of the table outside the forwardly converging hinge lines 10. It will be apparent that the stringers or channel irons 8 are susceptible of swinging motion and this is utilized to angularly adjust the same. Any desirable means may be provided for angular-1y adjusting these stringers or channel irons 8 for instance, I may provide adjusting screws as 11 tapped through the extreme outer ends of the same and bearing at their lower ends against piers as 6 (see Figs. 1 and 2 The upper ends of said adjusting screws 11 are equipped with handavheels 12 by the operation of which 'the screws can be turned to effect the adjustment of the said stringers or channel irons 8 the latter being, as will be clear, independently adjustable. Between the piers 6 and 6 I may arrange piers as 6 bridged by brackets as 7 to which the outer ends of the stringers or channel irons 8 are connected.

I have described in detail a simple mounting for the table. The latter might be mounted in other ways.

The primary portion 4 of the table is preferably, as hereinbefore indicated, disposed at a downward inclination from the head toward the tail portion of the table. Preferably the upper surface of this longitudinally extending primary portion 4 of the table is smooth and, owing to its inclination,

. the slime delivered thereonto will have a greater velocity than when passing over a horizontal plane and, owing to this velocity, there is naturally a decrease in volume, so that the pulp or slime-water will move in a thin layer, by virtue of which the fine parti' cles in the mass are brought into absolute contact with the smooth surface over which such mass travels. In addition to this, the heavier particles will adhere to the surface and stratification of the mass may also occur as the latter is gradually worked down said inclined portion 4.

The material may be supplied to the table in any suitable way, for example, by a feed distributer disposed at the head end thereof. I have shown such a feed distributer, the same consisting of a box as 13 fastened to I the extreme head end of the table and havslimes, or slime-water is distributed equally transversely of or across said portion 4. Along the sides of the portion 4 and throughout the complete length thereof are extended strips or flanges as 14 which prevent the lateral escape of the material thereon.

'by the areas 18 and 20, res

The pulp or slimes is discharged from the portion 4 into a pan or receptacle such as that denoted in a general way by 15 and shown clearly in Fig. 2. The pan or receptacle 15 consists of an end 16, a horizontal bottom 17, and two sides 18. The end 16 slopes downwardly from the portion 4 and its sides converge forward coincident with the inner ends of the sides 18 which are inclined upwardly from the bottom 17. The said pan or receptacle 15 contains a longitudinally extending ridge 19, the sides 20 of which are inclined downward and outward from the apex thereof, the forward end of said ridge being of wedge shape to facilitate its division of the oncoming ulp or slimes and overlying the end 16 of tlie pan 15. It will be understood that the surfaces 18 and 20 respectively converge downward, thereby forming gutters into which the two divisions or bodies of the pulp or slimes are received and are fed forward during the reciprocation of the table as a whole. It will be understood that the partially stratified material, after it leaves the inclined primary portion 4 of the table, asses down the inclined surface or end 16 o the pan or receptacle 15 and, when it enters said pan or receptacle, such mass is divided into two separate but equal portions by the divider or ridge 19, these two divisions being fed forward through the gutters or channels defined by the surfaces 18 and 20 respectively, but more especially along and then up the inclined surfaces 18 where they pass onto the duplicate rifiled portions 21, said riflled portions extending downward at an angle from the hinge lines 10. Between these riffled portions 21 is a horizontal area 22, the inner portion of which is at a point, the sides of the point being located between the areas 20. The heavier concentrates, after they leave the gutters or channels formed ctively, are fed onto this horizontal sur ace 22 and are moved along the same, bein finally delivered off the tail or extreme orward end of the table. The lighter concentrates aredischarged from off the head end of the table between the hinge lines 10 and the sides of the portion 5, leaving said end in accordance with their specific gravities. The very heaviest minerals are discharged from the head end of the table, of course, between the hinge lines 10, while the lighter values are discharged from said end at places outside of said hinge line. The wash water may be supplied by a pipe such as that denoted in a general way by 23, the horizontal branch 23 of said pipe extending longitudinally from the tail end of the table toward the head end thereof and terminatin substantially at the pointed inner end 0 the horizontal .surface or area of the two hinge lines 10. It will be clear that the rifiled portions 21 are downwardly inclined from said hinge lines. The inner ends of said portions 21 converge rearw'ardly upon acute angles and are furnished with ridges or ledges 14" continuations of the ridges or flanges 14. The sides of said ritfied portions 21 are also upon rearwardly converging angles of greater acuteness than those of the ends thereof, all as clearly shown in Fig. 2 The riffied portions 21 are provided with longitudinally extending riffles 24 and other riflies as 25 which join with the riffies 24, respectively. The rifiles 24 are substantially parallel with the respective hinge lines 10, while the rifiles 25 constituting practically continuations of the respective riffies 24 are parallel with the longitudinal axis of the table as a Whole.

While crosssectionally the several sets of rifiies are the same in area, the riffies 24 are separated a greater distance than the riffies 25, as shown in Fig. 2 and this relative variation in spaces between the said riffies can be accomplished by disposing the rear ends of the-rifl'les 25 or the forward ends of the riflles 24 in step order or along lines or planes angularly disposed and converging rearwardly the sets of rifiies 24 and 25 merging on diagonal lines which diverge relatively toward the opposite sides of the table. By virtue of this relation the refuse matter which is delivered over the sides of the portions 21 is permitted more freely to spread and is not retarded in its progress toward the sides of said portions 21 over which it it is discharged. The inclination, however, of the two adjustable or rifiied portions 21 is enough to retard the lateral flow of the pulp to an extent sufficient to insure complete stratification of the pulp or slimes, while such lateral How is further arrested by means of the upwardly inclined portions 26 at the extreme outer sides of said portions 21 and extending throughout the complete length of said sides.

The term settling as used in the claims is intended to designate that part or section of the table which performs the function of settling the solids out of the muddy water, that is, it clarifies slime water so that it is practically clear on the surface, while the term stratify designates that part described as the stratifying section which takes the so settled pulp and stratifies the pulp into lighter and heavier strata.

I may make the two portions of the table, as is common in this art, of a wooden or metallic frame of composite construction, the upper surface or working portion of the table being preferably made from linoleum or some equivalent substance covering boards laid on said frame and which are so shaped crosssectionally as to secure the various inclinations or angles on the finishing portion of the table. WVhere the hinge lines 10 are made these boards may be kerfed on their under sides. I do not believe it necessary to go into detail as to these features as they in themselves form no part of the invention which, as to that form of embodiment thereof selected for illustration in the accompanying drawings, has been fully set forth he-reinbefore.
